Yoga is a healing system of theory and practice. It is a combination of breathing exercises, physical postures, and meditation that has been practiced for more than 5,000 years.

While yoga evolved as a spiritual practice in Hinduism, in the Western world, a part of yoga, known as Asana, has grown popular as a form of purely physical exercise. Some Western forms have little or nothing to do with Hinduism or spirituality, but are simply a way of keeping fit and healthy.
